Oh yeah, coatings can get crazy. I’d generally stick to phosphate, nitride, or DLC. NiB is mostly a gimmick imo.

Nitrites are known to hold one nitrogen atom along with two oxygen atoms, whereas nitrates are known to hold one nitrogen atom, bonded to three different oxygen atoms.

Nitride will wear better, last longer, and have less friction than phosphate. There's a reason metal cutting tools (end mills, boring bar inserts, etc) have nitride coatings instead of phosphate. There is very minimal wear surface on a bolt carier.1:8. Nitride and midlength are better. This. Coatings mean a lot less than gas system length. And twist rate. 1:8 is a nice twist rate for handling most common 5.56 weights. Meh. 5.56 twist varies from 1:6 to 1:12. For most people anything between 1:7 and 1:9 is fine.
